Description

The aim of the project is gain insight into central issues in string theory. We address deep questions about the symmetries and the internal structure of the theory, and equally far-reaching questions where string theory and supergravity methods are developed in order to be applied to non-perturbative questions in strongly coupled gauge theory. Some of the current incarnations of these aims as shorter term topics are: A. The relation between so-called higher spin theories, string theory and free maximally supersymmetric gauge theory. B. The search for a more precise picture of the "holographic dualities" which seemingly relate quantum gravity theories in spacetime with quantum field theories on the boundary of spacetime. Three-dimensional gravity is used as a model. C. The spacetime picture of the elusive fate of instabilities signalled by the presence of so-called tachyons in string perturbation theory. D. The gauge theories with non-maximal supersymmetry which are amenable to study by finding "dual" geometries around so called branes, which intersect each other. We will work in theory collaborations locally and internationally, with postdocs and graduate students.
